What causes the front wheels to eat tires?

First, the so-called tire eating refers to the abnormal accelerated wear on the inside and outside of one or more tires, which is particularly fast than that of some other tires. When checking tires, we can see that the depth of other tires under the pattern or another part of the same tire will soon cause eccentric wear, leading to tire scrap.

Second, generally speaking, there are several reasons for eating the fetus:

1, four-wheel alignment is not allowed.

As a result, four tires are not on the horizontal and vertical straight lines required by the standard, so two wheels on the same side will eat tires when driving, or the front wheel or rear wheel will not go straight, and the vehicle will correct itself, resulting in abnormal friction between a certain part of a tire and the ground, which will accelerate wear.

2. Inappropriate toe-in adjustment can also lead to tire eating, that is, the front wheel leans slightly inward at an angle similar to the inner picture, which is the best angle for high-speed and stable driving. All cars have their own toe angle. If this angle is not adjusted properly, they will eat tires. The reason is the same as the first one.

3. Failure of the steering gear will also cause the tire to bite and run off.

4, the girder is uneven, and deformation can also cause eating tires. For example, some accident cars eat tires because the beam is deformed.

If the air pressure of each tire is too different, it will eat the tire.
